Foldable Display Sensor Exposure via Dynamic Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices do not adequately address the functionality of a display unit made of a flexible base material that can fold and transform, particularly in terms of effectively utilizing folding transformation for functional execution.
Innovation Solution
A display device with a display unit that is at least partially foldable and transformable, including a display surface for image display, a body unit on the back face, and a sensor with a detecting surface that can be uncovered by folding transformation of the display unit, allowing the device to switch between covering and uncovering states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sensor is provided on the display device, then the device can perform sensing functions, but the sensor requires a detecting surface that conflicts with full-screen image display
Solution Approach 1:
The display unit is designed to be flexible and transformable, capable of switching between a planar state (for full-screen display) and a folded state (for sensor exposure). This dynamic transformation allows the same display unit to serve dual purposes: maintaining full-screen image display when planar and uncovering the sensor when folded, thereby resolving the conflict between sensing function and display area.
2Area of stationary object
If the detecting surface is covered to maintain full-screen display, then the display area is maximized, but the sensor cannot perform its sensing function
Solution Approach 1:
The flexible display unit enables dynamic state switching between covering and uncovering the sensor. When the display unit is in the planar state, it covers the sensor to maximize display area. When folded, it uncovers the sensor to enable sensing function. This dynamic transformation ensures both full-screen display and sensor reliability are maintained at different operational states.
3Reliability
If a notch or separate compartment is provided for the sensor, then the sensor can be accessed, but the full-screen image display is compromised
Solution Approach 1:
Instead of providing a static notch or separate compartment that permanently reduces display area, the invention uses a flexible display unit that dynamically uncovers the sensor through folding transformation. This approach maintains the full-screen display area in the planar state while enabling sensor accessibility when folded, eliminating the need for permanent notches or compartments.
Solution Approach 2:
The display unit is constructed with flexible materials that allow it to be folded and transformed. This flexibility enables the display unit to act as a movable cover for the sensor, uncovering it when folded without requiring permanent structural modifications like notches or separate compartments, thereby preserving the full-screen display area.

AI summary
A display device includes: a display unit at least partially foldable and transformable, and including a display surface that displays an image; a body unit provided to a back face of the display unit; and a sensor having a detecting surface positioned to be covered with the display unit or the body unit. The display device is switchable between a covering state in which the detecting surface is covered and an uncovering state in which the detecting surface is uncovered. The uncovering state is switched from the covering state by folding transformation of the display unit.
